![]() ![]() CLICK HERE for information on fuel pumps carried by Radium Engineering. However, there are many other make/model of pumps that fit this same fitment and electrical connection that can potentionally work as well. Traditional Brushed Fuel Pump Compatibilityĭesigned specifically for the AEM 50-1200 and Walbro GSS342 fuel pumps. The installer must provide their own fuel pumps and perform final assembly. Any combination of 1, 2, or 3 pumps can be configured. The 20-0572 fuel pump hanger is compatible with both brushed and brushless fuel pumps. However, custom wiring will be necessary to control a third pump.įuel pump wiring is specific to which fuel pump(s) is used and which trigger strategy will be implemented. In some cases, two aftermarket pumps can use the OEM wiring. The factory GT-R fuel pump hanger utilizes two fuel pumps. The factory temperature and fuel level sensors are reused. Furthermore, the in-tank wiring is insulated with high quality chemically resistant ETFE. Electrical hardware is included for the fuel pump(s) and OEM sensors. ![]() Non conductive anodized aluminum acorn nuts are provided to prevent any accidental short circuiting. These serviceable connections are hermetically sealed and impervious to all standard and exotic fuels. The Radium fuel pump hanger features custom designed stainless electrical studs that easily handle the high current demand that multi-pin bulkhead connectors lack. Since the fuel hanger eliminates the non serviceable post pump filter, an aftermarket filter is required to be installed downstream (see 20-0851-0X Fuel Hanger Feed Kits below). ![]() Other adapter fittings are available and are sold separately.įILTRATION: Sock filters are provided for all 3 fuel pump inlets. To clear the OEM fuel pump cover plate, the standard fuel hanger kit includes low profile swiveling adapters that convert to 6AN male, along with short 6AN PTFE hoses and adapters for easy connection to the OEM fuel piping. The 1-way fill valves flow 355LPH each (1,065LPH total).Īll of the components work together to keep the collector box filled with fuel and prevent fuel pump starvation. Additionally, the Radium Engineering 20-0572 incorporates three 355LPH one-way fill valves integrated to the bottom of the collector box (shown below) that allows fuel in, but not out. In addition to the venturi jet pumps scavenging fuel, the pressure regulator return also keeps the large collector box filled with fuel. NOTE: The fuel filter provided in the 20-0851-03 and 20-0851-05 feed kits (listed below) feature an integrated check valve. If it is important for fuel pressure to hold steady after the engine is shut down, install one of these CHECK VALVES somewhere in the fuel system. Take this fuel loss into consideration when sizing the fuel pumps.Ģ. ![]() Depending on fuel pressure, the venturi jet pumps will consume 15-45 LPH. This allows the pumps to be upgraded without fuel pressure concerns.ġ. By reconfiguring the venturi jet pump plumbing, Radium Engineering has kept their functions without impacting the returning fuel from the regulator. When the fuel pumps are upgraded, these venturi jet pumps become a restriction in the return line, resulting in elevated fuel pressures and unreliable regulator performance. They supply fuel from both sides of the tank to the OEM pump bucket and are driven by fuel returning from the regulator. The GT-R saddle bag style fuel tank uses two OEM venturi jet pumps. Gasoline, Methanol, and Ethanol Compliant Radium Engineering recommends reviewing the installation instructions (link above) before purchasing. The system is compatible with alternative fuels such as methanol, ethanol, E85, etc. The fuel pump outlet port is -10AN ORB female threaded and includes a 6AN male adapter, while the return port is -8AN ORB female threaded and includes a 6AN male adapter. This ensures that fuel starvation does not occur, even during aggressive driving. The pumps are housed in an aluminum collector box that is kept full during operation. No permanent vehicle modifications are required for installation. The Radium Engineering fuel hanger completely replaces the factory in-tank fuel pump unit in the R35 GT-R and permits up to three 39mm diameter aftermarket pumps (brushed or brushless) to supply fuel to the engine. This in-tank fuel hanger is compatible with the following: Nissan (R35) GT-R ![]()
